About:I've been an experimental high-energy physicist for 20 years (since I started graduate school in 1988). I got my BS in physics from UCLA, my Ph.D. at Caltech, and did a post-doc at UBC before moving to SLAC. Being an experimentalist means that I got to learn how to use machine tools, to fabricate little parts and jigs with a mill and lathe, and to deal with Real Engineers to design and construct experiments. This was a great learning experience, and I've been putting it to good use ever since. Since I got together with my wife, I've been doing assistive technology projects for her. Now I'm starting to do the same to make taking care of our daughter easier. Designing stuff is great fun, but actually taking it from two to three dimensions, especially for someone else, is even better.

i checked it out and it seems that i wasn't exactly clear about what i meant, i think a better way to put it is to say manipulate a cloud of free flowing plasma. Not necessarily in a confined space but just flowing around.

Since plasmas are collections of charged particles, you can either use electrostatic fields (plates or grids at voltage) or magnetic fields to manipulate them. If you don't keep it in vacuum, the charges will interact with air molecules and be absorbed.

Hi, I saw on another site your name, I wanted to get a van for my Mom to drive that she can put her wheelchair in. I also use a wheelchair when we go to places with a lot of walking. I have arthritis and fibromyalgia and tourettes syndrome and autistic and more. My mom also drives her Mom places and her mom is in a wheelchair or a scooter. When my mom has to drive her mom she has to go without her own wheelchair and driver her moms car that has her moms scooter in it. And a lot of times we just stay home because if she walks to much she is in a LOT of pain, and I cant do all the walking either. I have arthritis in my feet and legs and MAN does it hurt to walk around. I just wanted to help her and get her a van because ours has stopped working. She has a suitcase ramp she uses in her van. Shes a really good Mom. I joke and call her my Ood, from Dr. Who. She does so much for me, and for her Mom and Dad who are 78 and she really deserves this.

It is the LIDAR facility in Washington. Which balances the two lasers in a vacuum with tune out notch at the crystal return mirror resonant frequency and use the corrective drive as the gravity signal information.

Speaking with my friend, the facility appears to have failed to confirm Einstein's gravity waves from nearby orbiting dual suns or sun with black hole.

I think that rather than "LIDAR" (which is used by the police to catch speeders) you are thinking of the LIGO facility in Hanford, Washington. It uses a Michelson-Morley interferometer set up, with Fabry-Perot cavities on each arm, to look for gravitational waves.

Together with a similar detector in Livingston, Louisiana, it is looking for gravitational waves from astrophysical sources such as merging neutron stars or merging black holes. At present, the sensitivity of LIGO is still not quite good enough (there's too much background noise) to actually observe such signals.

No problem! I've used McMaster-Carr as a resource for about fifteen years, now, and haven't had any problems. Their catalog runs to something like 3,000+ really dense pages, with everything from individual nuts up to forklifts.

I wanted to ask a fairly random question here in order not to derail the established thread as it's so far off-topic. In the vegetarian thread, you wrote "I am completely in support of your opinions about CAFOs. The conditions there are appalling -- if (when) human beings were treated that way, the perpetrators were tried and executed."

I'm curious as to where you stand on the death penalty - given what I know about your general political slant I would think it likely that you oppose it across the board. However, (though I realize it doesn't *necessarily* reflect anything about what you think), I wasn't as sure after reading your comment. I found the thought of what Nacho calls a "Lotus Eating Leftie" tacitly finding capital punishment acceptable on a thread about animal rights rather interesting. Thus my curiosity. :D

(If you're not comfortable with the question (I don't know that I would be!), apologies and I can remove the comment.)
